T HIS experiment was conducted during 2020 and 2021 on Samany date palms grown in new reclaimed sandy soil at private orchard located at Al Assiuty valley, Assuit, Egypt, to improve yield and some physical and chemical fruit quality by strand thinning (shortening 25% of length of all strands from the terminal tips at pollination and one month after pollination or removing 25% of total strands from the center of the bunch at pollination and one month after pollination. These results indicated that the control gave the highest bunch and total yield than the other treatments but all thinning treatments increased most of physical properties; fruit weight, flesh weight, fruit length, and diameter and thickness . Also improved the chemical properties such as TSS, total sugars, and reducing sugars. Strand thinning by removal 25% of the total number of strands at month after pollination gave the highest physical and chemical properties.

T HE fruit quality of grapevines is a great importance for local consumption and export. Shoots and clusters thinning are substantial agricultural practices in grapevines to improve the berries quality. Herein, 10-years-old King Ruby grapevines were examined in two successive seasons. Four different levels of shoots number were applied (48, 42, 36, and 30, shoots/vine) with two different levels of clusters (30 and 24 clusters per vine). Results showed that the gradual decrease of shoots and clusters/vine improved vegetative growth parameters (shoot length and leaf surface area), total chlorophyll content, and microclimatic characteristics (light intensity, air temperature, and relative humidity); however, decreased yield/vine was observed. Consequently, enhanced chemical properties of berries (SSC, SSC/acid ratio total sugars, total anthocyanins, and total phenols) were obtained. In addition, an improved coefficient of wood ripening and total carbohydrates in canes was recorded. Moreover, the progressive increase in the number of shoots/vines in parallel with the decreased number of clusters/vine raised the cluster weight, cluster length, width, berry weight, length, and width. The thinning application of 30 shoots + 24 clusters per vine collectively achieved the significant highest values of vegetative growth, microclimatic parameters and berries quality, therefore, it could be recommended for application in King ruby vineyards under the Egyptian climatic.

P ROPAGATION of cucurbits via grafted seedlings exhibits an increasing trend in vegetable cultivation in Egypt. This is due to the limited cultivated area, intensive cultivation, and increasing stress leading to problems that negatively affect production. While the investigations for determining the accurate fertilization amount of the grafted plants are still scarce. Therefore, this experiment was conducted in a private farm located in Badr city, El-Behera governorate, Egypt, to evaluate the performance of non-grafted (control) and grafted cantaloupe plants ( Cucumis melo var. cantaloupenses, cv. Marella F1 hybrid) onto four rootstock cultivars (Cobalt, Ferro, Star, and 6001) then fertilized with nitrogen (N), phosphorus (P), and potassium (K) at rates of 60, 80, 100, 120, and 140% of these nutrients recommendations for cantaloupe fertilization during the two successive growing seasons of 2018 and 2019. The results indicated that grafting cantaloupe plants onto the tested rootstocks had promoted a higher vegetative growth manifested as plant length, leaves number, shoot fresh and dry weight, stem diameter, and root dry weight, as well as raising leaves content of nitrogen, phosphorus, potassium, and the greenness index (chlorophyll readings, SPAD) along with boosting the average fruit weight, and early and total yield than the control when all were fertilized by any of the applied fertilization rates. Worthy, rootstocks of Cobalt and Ferro provided the greatest superiority in all investigated growth and fruit yield characteristics of the cantaloupe plant through fertilizing by the 140% NPK fertilization rate.
